ADVTemplate Class

Reklam temamızı temsil etmesi amacı ile bir sınıf hazırladık. Bu sınıfın görevi, reklam temasının şemasını XML dosyasından okuyarak, gerekli bilgileri kendi içerisinde barındırmasını sağlamak. Reklam yöneticisi tarafından sürekli kullanılacağı ve bir probelme el vermemesi açısından, isReady fonksiyonu ile de hazır olup olmadığı test edilebilir kılındı. Dolayısı ile, herhangi bir memory overflow olayında veya geç okunma olayında kullanıcıya hata yerine sistem kendi kendini yenileyerek her defasında kesin sonuç geri döndürecek.
Hazırlamış olduğum sınıfın kodu şöyle:

/**
 * This class is used to represent a ADV Template to provide required fileld and values along
 * the reqistration process of the advertisement.
 * This class uses Domdocument object library to load xml schema file.
